摘　　要：白蜡吉丁啮小蜂Tetrastichus planipennisi Yang是国际重要检疫性害虫白蜡窄吉丁Agrilus planipennis幼虫期内寄生蜂。在辽宁省绒毛白蜡Fraxinus velutina苗圃,调查受白蜡窄吉丁危害的植株中白蜡吉丁啮小蜂越冬代自然寄生率,发现其对越冬代白蜡窄吉丁的平均寄生率为(9.25±1.78)%,受害树的有蜂株率为80%。说明白蜡吉丁啮小蜂对白蜡窄吉丁具有一定的自然控制效果,是一种良好的生防控制因子,值得在生物防治中大力推广应用。Tetrastichus planipennisi Yang(Hymenoptera:Eulophidae)is an endoparasitoid of Agrilus planipennis Fairmaire(Coleoptera:Buprestidae)larvae,which is an important international quarantine pest.The natural parasitism rates of over-wintered T.planipennisi parasitized on the A.planipennis were investigated in Fraxinus velutina trees in Liaoning province,China.The results showed that the average parasitism rate of the parasitoid was(9.25±1.78)%,and the percentage of trees with the parasitoid was 80%.It indicates that the parasitoid had good natural control effect and could be an effective biological control agent against the emerald ash borer,and it is worthy to be popularized and applied in biological control of A.planipennis.
